Similar to antlers, horns are often used by males in fights and displays during the breeding season. In members of the family Bovidae, horns develop from or over the frontals. They possess their own centers of ossification and fuse secondarily to the skull bones. They are not attached to the skull and are known as ossicones. Horn cores begin as small bony growths under the skin, over the skull, in the subcutaneous connective tissue. Neither the sheath nor the core are ever shed, and in many species, the horns never stop growing.

The growth of horns is completely different from that of antlers. Unlike antlers, horns are never branched, but they do vary from species to species in shape and size. Horns are composed of a bony core covered with a sheath of keratin. Horns occur in males of all species of Bovidae, and females often bear them too. Often species with large canines have small antlers or are missing antlers altogether. Curiously, some cervids have large canine teeth, which are used in sexual displays and fighting. Males then are without antlers for a few months in late winter until the cycle begins again. As a result, the pedicel loses calcium, weakening the point of connection between it and the antler, and eventually the antlers are shed. In winter, pituitary antler-growth hormone stimulation decreases as day length shortens, and androgen secretion lessens. Males use their full-grown antlers during the breeding season in social interactions in competition for females. The antlers also are stained during this action, giving them the brown, polished, wooden look. The velvet dies and is removed in part by the animals rubbing and thrashing their antlers against vegetation.

As they grow, antlers are covered with skin and soft hair called velvet, which carries blood vessels and nerves.Īs antlers near the end of the growing process, spongy bone in their outer edges is replaced by compact bone, while their centers become filled with coarse, spongy, lamellar bone and marrow spaces. Early in their development, antlers have high water and protein content. In the northern hemisphere increasing day length also plays a role. Secretions from the pituitary initiate the growth in April or May. The growth cycle is regulated by testicular and pituitary hormone. Antlers grow from pedicels, which are bony supporting structures that develop in the lateral region of the frontal bones. They are present only in males (with the exception of caribou) and are capable of growing astoundingly large. AntlersĪntlers are one of the most easily recognized characteristics of the family Cervidae. Antlers are a pair of bony, branched structures that protrude from the frontals of the skull of animals and are shed annually horns are also paired and protrude from the frontals, but they are permanent, unbranched, and made up of a bony core and a keratinized sheath. The terms horns and antlers are often used interchangeably, but in reality, they refer to quite different structures.
